Final answer:
Statement C is false in regard to zeroing a transducer because zeroing is necessary for initial setup to ensure accurate measurements. Statements A, B, and D correctly describe the zeroing process, where the transducer is opened to air, a button is pressed to initiate zeroing, and the monitor should read '0' after zeroing.
Step-by-step explanation:
The process of zeroing a transducer, typical in medical and engineering contexts, involves establishing a baseline measurement so that subsequent readings reflect true relative pressure. The correct procedures for zeroing a pressure transducer are as follows:
- A) It is true that the transducer must be open to air to perform zeroing, as this sets the reference point to atmospheric pressure, which is the 'zero' level for gauge pressure readings.
- B) Pressing a button on the monitor to initiate zeroing is also correct, allowing the monitor to recognize the atmospheric pressure as the zero reference.
- C) The statement that zeroing is not necessary the first time the transducer is set up is false. Zeroing is a critical step in the initial setup to ensure accurate pressure readings from the start.
- D) Finally, when the transducer is open to air, the monitor should indeed read "0", indicating that it is properly zeroed to atmospheric pressure.
Therefore, the statements in options A, B, and D are true regarding the zeroing of a transducer, while the statement in option C is false.
The correct answer to the question of which statement is false in regard to zeroing a transducer is C) Zeroing is not necessary the first time you set up and use a pressure transducer.
